M PROVEM ENT IN DOU BLE-CYLl N DER BOILERS FOR HOT-WATER APPARATUS.

Specification forming part of Letters Patent No. 11,926, dated November14, 1854.

To atZZ whom it may concern.-

Be it known that 1, WILLIAM BEEBE, of New York, county of New York, andState of New York, have invented a new and Improved Mode of ConstructingBoilers for Heating Water, called an Improvement in Double-CylinderBoilers; and I do declare that the following is full and exact description thereof, reference being bad to the accompanying drawings, and tothe letters of reference marked thereon.

The nature of mv invention consists in constructing two boilers, onewithin the other, (marked A and 13 on the accompanying drawings,) theouter boiler A to be supplied by a reservoir K, which will receive itswater from the public water-works, and the inner boiler B to be suppliedby a reservoir L, into which the water will be thrown by a force-pump orderived from the root of the house, the outer boiler A to be connectedin the usual way with an ordinary kitchen-range, and the water in theinner boiler B to derive its heat from the water which surrounds it inthe outer boiler A.

The object of my in vention is to supply hot water to the upper storiesof houses in neighborhoods that are on too high'ground to admit of theirreceivingasupply througout from the public water-works.

To enable others skilled in the art and use of my invefition,I willproceed to describe its construction and operation.

I construct my boiler in the cylindrical or any other of the known formsand place one within the other, as shown at Figures 1, 2, and 3.

Fig. 1 is a perspective view. Fig. is a transverse section. Fig. 3 is avertical section.

I place one boiler within another, although separate and distinct, theoutside boiler being supplied by one reservoir whose level is belowrooms or apartments in which water is wanted. The inside boiler issupplied from a reservoir whose level is above the other reservoir andon a level or above rooms or apartments in which water is desired.

The outside boiler A is connected with a fire or range in the usualmanner, which heats the water in theboilerA andaround the outside ofboiler B, thereby communicating its heat to the water in the boiler B tothe same temperature of that in the boiler A.

I supply the inside boiler B with water by a pipe C from the upperreservoir at the bottom of the boiler A by a coupling or connection D,going through the center of the lower head E of boiler A and connectingwith the lower head F of boiler 13, making it watertight.

The discharge from the boiler B is accomplished in the same manner asthe supply, viz., by means of a coupling or connection G, going from theupper head H of boilerB and through the upper head I of boiler A, thenceby means of pipes in the usual way.

hat I claim as my invention, and desire to secure by Letters Patent, is'

The combination of two boilers, one within the other, and tworeservoirs, one above the other, arranged with one set of connectionswith a kitchen-range, so that the upper part of a house may be suppliedwith hot water by means of the upper reservoir, which will derive itssupply of coldwater either from the roof or from a force-pump, while thelower part of the house will be supplied by means of the lowerreservoir, which will derive its supply from the public water-works.

W'M. BEEBE.
